Message Title

I've attached a test case that reproduces the problem. Unfortunately, I don't know how to do assertions on hibernate logs, or on the total number of queries that were run, so JUnit always considers it as passing.

When run it displays, the faulty behavior by printing the following logs (1 select to fetch all the containers, then N extra selects to fetch the children of each container independently):

Hibernate: 
    select
        container0_.ID as ID1_1_ 
    from
        CONTAINER container0_
Hibernate: 
    select
        childrenby0_.PARENT_ID as PARENT_I4_0_0_,
        childrenby0_.ID as ID1_0_0_,
        childrenby0_.TYPE as formula0_0_,
        childrenby0_.ID as ID1_0_1_,
        childrenby0_.CONTAINER_ID as CONTAINE2_0_1_,
        childrenby0_.TYPE as TYPE3_0_1_ 
    from
        CHILDREN childrenby0_ 
    where
        childrenby0_.PARENT_ID=?
Hibernate: 
    select
        childrenby0_.PARENT_ID as PARENT_I4_0_0_,
        childrenby0_.ID as ID1_0_0_,
        childrenby0_.TYPE as formula0_0_,
        childrenby0_.ID as ID1_0_1_,
        childrenby0_.CONTAINER_ID as CONTAINE2_0_1_,
        childrenby0_.TYPE as TYPE3_0_1_ 
    from
        CHILDREN childrenby0_ 
    where
        childrenby0_.PARENT_ID=?
Hibernate: 
    select
        childrenby0_.PARENT_ID as PARENT_I4_0_0_,
        childrenby0_.ID as ID1_0_0_,
        childrenby0_.TYPE as formula0_0_,
        childrenby0_.ID as ID1_0_1_,
        childrenby0_.CONTAINER_ID as CONTAINE2_0_1_,
        childrenby0_.TYPE as TYPE3_0_1_ 
    from
        CHILDREN childrenby0_ 
    where
        childrenby0_.PARENT_ID=?

However, if you comment out Container.postLoad, it results in the expected behavior (1 select to fetch all the containers + 1 select to fetch all of the children of all containers in one query):

Hibernate: 
    select
        container0_.ID as ID1_1_ 
    from
        CONTAINER container0_
Hibernate: 
    select
        childrenby0_.PARENT_ID as PARENT_I4_0_1_,
        childrenby0_.ID as ID1_0_1_,
        childrenby0_.TYPE as formula0_1_,
        childrenby0_.ID as ID1_0_0_,
        childrenby0_.CONTAINER_ID as CONTAINE2_0_0_,
        childrenby0_.TYPE as TYPE3_0_0_ 
    from
        CHILDREN childrenby0_ 
    where
        childrenby0_.PARENT_ID in (
            select
                container0_.ID 
            from
                CONTAINER container0_
        )
